[#173] In the atmosphere of the primitive earth there was no ________
Correct Answer

[#174] Winds and air currents differ in the aspect that ________
Correct Answer

(D) Winds are horizontal movements of air while air currents are the vertical movements of air

Explanation

Solution: Winds and air currents differ in the aspect that Winds are horizontal movements of air while air currents are the vertical movements of air. Air currents are concentrated areas of winds. All winds result from horizontal differences in air pressure.

[#175] Lapse rate is related to the decrease of ________
Correct Answer

(C) Temperature at 1°F for an ascent of 330 feet

Explanation

Solution: Lapse rate is related to the decrease of Temperature at 1°F for an ascent of 330 feet. The lapse rate is the rate at which an atmospheric variable, normally temperature in Earth's atmosphere, changes with altitude.
